- ELMBAK, SELMBAK - EISPACK routine. This subroutine forms the
- eigenvectors of a REAL GENERAL matrix by back transforming those of the
- corresponding upper Hessenberg matrix determined by ELMHES.

- On INPUT
-
- NNNNMMMM must be set to the row dimension of two-dimensional array parameters
- as declared in the calling program dimension statement.
-
- LLLLOOOOWWWW and IGH are integers determined by the balancing subroutine BALANC.
- If BALANC has not been used, set LOW=1 and IGH equal to the order of
- the matrix.
-
- AAAA contains the multipliers which were used in the reduction by ELMHES
- in its lower triangle below the subdiagonal.
-
- IIIINNNNTTTT contains information on the rows and columns interchanged in the
- reduction by ELMHES. Only elements LOW through IGH are used.
-
- MMMM is the number of columns of Z to be back transformed.
-
- ZZZZ contains the real and imaginary parts of the eigen- vectors to be back
- transformed in its first M columns. On OUTPUT
-
- ZZZZ contains the real and imaginary parts of the transformed eigenvectors
- in its first M columns. Questions and comments should be directed to B.
